Quicktime malfunctioning after new install?

My tutorials don't work properly now; I've tried the newest quicktime, the one that came with them, and some inbetween (uninstalling each time). Althought the individual files work and play fine, there is a "starthere.exe" that acts as a hub and menu. I need it because there are dozens of short files making up each one. When I try and launch them from the hub, I get a warning "quicktime has encountered an unexpected error and had to close..." with the newest quicktime, and various artefacts with the packeged versioin.

it's true that the .exe is not part of quicktime. It's an application with a menu, which opens the quicktime movies. But, the error does reference quicktime I believe, making me think that is where the problem lies. Also, the fact that there are different errors depending on the version I use... possibly I'm wrong about that?
